“…The nanoparticles with more surface area have been shown to release silver ions at a higher rate, which is an important factor for high antibacterial activity [70]. Antibacterial activity of AgNPs have been studied against the multidrug resistant bacteria such as P. aeruginosa , E. coli , Streptococcus pyogenes , S. aureus , Klebsiella pneumoniae , Salmonella species, and Enterococcus species [71,72]. This bactericidal effect, mostly, is attributed to the inhibition of cell wall synthesis, protein synthesis mediated by the 30S ribosomal subunit, and nucleic acid synthesis.…”

Infectious diseases pose one of the greatest health challenges in the medical world. Though numerous antimicrobial drugs are commercially available, they often lack effectiveness against recently developed multidrug resistant (MDR) microorganisms. This results in high antibiotic dose administration and a need to develop new antibiotics, which in turn requires time, money, and labor investments. Recently, biogenic metallic nanoparticles have proven their effectiveness against MDR microorganisms, individually and in synergy with the current/conventional antibiotics. Importantly, biogenic nanoparticles are easy to produce, facile, biocompatible, and environmentally friendly in nature. In addition, biogenic nanoparticles are surrounded by capping layers, which provide them with biocompatibility and long-term stability. Moreover, these capping layers provide an active surface for interaction with biological components, facilitated by free active surface functional groups. These groups are available for modification, such as conjugation with antimicrobial drugs, genes, and peptides, in order to enhance their efficacy and delivery. This review summarizes the conventional antibiotic treatments and highlights the benefits of using nanoparticles in combating infectious diseases.

“…Despite the common belief that biological synthesis implies a lack of control for Ag + reduction and poor shape control, Jinu et al [ 110 ] demonstrated the synthesis of cubic and triangular shaped 20 nm AgNPs using Solanum nigrum leaf extract. The nanoparticles had a contributing effect along with the antimicrobial plant extract towards six MDRB strains.…”

Biogenic Nanosilver against Multidrug-Resistant Bacteria (MDRB)

Multidrug-resistant bacteria (MDRB) are extremely dangerous and bring a serious threat to health care systems as they can survive an attack from almost any drug. The bacteria’s adaptive way of living with the use of antimicrobials and antibiotics caused them to modify and prevail in hostile conditions by creating resistance to known antibiotics or their combinations. The emergence of nanomaterials as new antimicrobials introduces a new paradigm for antibiotic use in various fields. For example, silver nanoparticles (AgNPs) are the oldest nanomaterial used for bactericide and bacteriostatic purposes. However, for just a few decades these have been produced in a biogenic or bio-based fashion. This review brings the latest reports on biogenic AgNPs in the combat against MDRB. Some antimicrobial mechanisms and possible silver resistance traits acquired by bacteria are also presented. Hopefully, novel AgNPs-containing products might be designed against MDR bacterial infections.

Many strategies have been adopted to improve the photoinduced features of zinc oxide nanostructures for different applicationf ields. In this work, zinc oxide has been synthesised and decorated by plasmonicm etal nanoparticles to enhance its photocatalytic activity in the visible range. Furthermore, an insulating layer of SiO 2 has been grown between the surfaceo fzinc oxide nanoflakes and silvern anoparticles. As ynthetic procedure that allowst he accurate modulation of the insulatingl ayer thickness in the range 5-40 nm has been developed. Evidences highlight the crucial role of the SiO 2 layer in dramatically increasing photocatalytic water oxidation promotedb yt he nanostructure under both UV and visible illumination. An ideal thickness value of about1 0nmh as been demonstratedt og uarantee the plasmon-induced resonance energy-transfer process and to quench the Fçrster resonance energy-transfer mechanism; thus, optimising the local surfacep lasmon resonance effect and water oxidation properties.[a] Dr.
